Frequency Analysis of Submerged Cylindrical Shell near the Rigid Wall with Hydrostatic Pressure

Abstract Fluid boundary is quite common to be noted in engineering, for example, water tank, or the ocean. The tank wall could regarded as rigid wall. Besides, structures submerged water, hydrostatic pressure actually existes, and its effect important especially big level. In this work, hysrostatic are both accounted, natural frequency predicted cylindrical shell near with high pressure. Results show that will reduce modal frequency. And more small increase of distance between It’s finally ignored while gap large enough. Hysrostatic also frequency, influence obvious
